A Problem That Never Really Went Away

There is a tendency to think of slavery as something distant, something rooted firmly in the past or confined to parts of the world far removed from everyday British life. It sits in history books, in documentaries, in the language of abolition and progress. It is not something most people associate with modern Britain, or with the streets, workplaces and systems that shape daily life.

And yet, the latest findings from the Independent Anti-Slavery Commissioner suggest something far more uncomfortable. Modern slavery is not only present in the UK, it is rising, and doing so at a pace that is becoming harder to ignore. Referrals of suspected victims have reached record levels, with more than 23,000 cases identified in 2025 alone. That figure has nearly doubled in just a few years, and the expectation is that it will continue to grow rather than stabilise.

This is not a sudden emergence. It is a problem that has been building quietly, largely out of sight, but increasingly woven into the fabric of the modern economy.

Not Somewhere Else, But Here

One of the most persistent misconceptions about modern slavery is that it exists elsewhere. That it is something imported, something external, something that happens beyond the borders of everyday British experience. The reality is far closer to home.

Exploitation linked to modern slavery has been identified across a wide range of sectors within the UK, including agriculture, construction, hospitality, car washes and domestic work. It exists in both urban and rural settings, often hidden in plain sight. It does not always announce itself in obvious ways. More often, it sits beneath the surface, embedded within legitimate industries and supply chains.

Perhaps most strikingly, a growing number of victims are British nationals. This is not solely an issue of migration or international trafficking, although those factors remain significant. It is also about vulnerability within the UK itself, about people who fall into situations where exploitation becomes possible.

That shift changes the conversation. It moves the issue from something that feels external to something that is undeniably domestic.

Vulnerability in a Changing Economy

At the centre of the rise is a familiar but deeply troubling pattern. Exploitation thrives where vulnerability exists. The cost of living crisis, rising housing pressures and increasing levels of financial instability have created conditions in which more people are exposed to risk. Debt, insecure employment and lack of stable accommodation can all make individuals more susceptible to coercion, manipulation or false promises of work.

Modern slavery does not begin with chains. It often begins with an offer, an opportunity that appears to provide a way out of a difficult situation. That is what makes it so effective. It adapts to circumstances, finding points of weakness and building from there. As economic pressure increases, so too does the pool of people who can be targeted.

The Role of Technology in a New Form of Exploitation

What distinguishes the current moment from previous decades is the role of technology.

The Independent Anti-Slavery Commissioner has highlighted how digital platforms, artificial intelligence and new forms of payment are reshaping how exploitation operates. Recruitment can now take place online, through social media or informal job networks that reach large numbers of people quickly. Communication between those orchestrating exploitation and those being exploited can happen remotely, reducing the need for direct physical control.

Financial transactions can be obscured through digital systems, making it harder to trace the flow of money. At the same time, technology allows for greater coordination, enabling exploitation to operate across locations and at a scale that would have been far more difficult in the past.

This is not a return to old forms of slavery. It is something that has evolved alongside the modern world, using its tools and infrastructure to remain hidden.

A System Struggling to Keep Pace

The UK does not lack laws or frameworks designed to address modern slavery. There are systems in place, from identification and referral mechanisms to enforcement and victim support structures. In theory, these provide a comprehensive response. In practice, the situation is more complex.

The Independent Anti-Slavery Commissioner has raised concerns that the UK’s response has begun to stagnate. The scale of the problem is increasing, while the systems designed to address it are struggling to keep up. This is not necessarily due to a lack of intent, but to the challenge of responding to an issue that is both evolving and expanding.

Policing, support services and regulatory bodies are all operating within wider pressures. Resources are stretched, priorities are competing, and the nature of modern slavery itself makes it difficult to detect and disrupt.

The result is a gap between what exists on paper and what is experienced in reality.

The Part We Do Not See

Perhaps the most unsettling aspect of modern slavery is how much of it remains unseen.

The figures that are reported represent identified cases, situations where something has been recognised and brought into the system. They do not capture the full extent of the problem. Many victims never come forward. Many situations remain hidden, either through fear, lack of awareness or the subtlety of the conditions involved.

This means that the true scale is likely higher than any official number suggests.

It also means that modern slavery can exist alongside everyday life without being immediately visible. It can sit behind familiar settings, within industries that appear ordinary, sustained by systems that are not designed to expose it easily.

A Question About the Systems Around Us

What makes this issue particularly significant in the current moment is how closely it connects to broader questions about the systems people rely on. The UK has legal frameworks in place. It has institutions designed to protect vulnerable individuals. It has enforcement bodies tasked with identifying and addressing exploitation. None of these has disappeared.

And yet, the number of people being drawn into situations of exploitation is increasing.

This does not point to a single failure. It points to a more complex reality in which systems exist, but are being tested by changing conditions. Economic pressure creates vulnerability. Technology enables new forms of control. Enforcement struggles to keep pace with both.

In that space, exploitation finds room to grow.

A Problem That Demands Attention, Not Distance

It would be easier to treat modern slavery as an issue that exists at the edges, something separate from the everyday concerns of most people. But the evidence suggests that it is more closely connected to the conditions shaping modern Britain than many would expect.

It is tied to how people work, how they live, how they access opportunities and how they are supported when those systems do not function as intended.

That is what makes it difficult to ignore. Not simply the scale of the problem, but the way it reflects deeper pressures within society. Modern slavery has not reappeared. It has adapted.

And as it adapts, it raises a question that is harder to answer than it first appears. If the systems designed to prevent exploitation are in place, why is it still increasing?

Heathrow’s Third Runway Back in the Spotlight: A Tale of Growth, Controversy, and Future Challenges

The long-debated third runway at Heathrow Airport has returned to the headlines as Chancellor Rachel Reeves announced renewed government support for the expansion. This endorsement comes amid promises to boost the UK’s global connectivity and stimulate economic growth, reigniting a decades-old debate that has deeply divided policymakers, environmentalists, and local communities. While proponents argue that the project is essential for the country’s future, opponents are raising concerns about its environmental and social impacts. To fully understand the significance of this development, it’s important to delve into Heathrow’s rich history and the contentious journey of the third runway proposal.

The Birth of Heathrow: From Hamlet to Aviation Hub

Before Heathrow became the bustling global hub we know today, it was a small hamlet known as Heath Row, situated west of London. This unassuming village, with its farms and open fields, was chosen in the 1930s for the establishment of an airfield. Initially, it was the site of the Great West Aerodrome, a private facility operated by Fairey Aviation. However, during World War II, the British government requisitioned the area, ostensibly for military purposes. The war ended before the airfield was fully operational, and in 1946, it was repurposed as a civilian airport under the name London Airport. It wasn’t until the 1960s that the name Heathrow was adopted, paying homage to the hamlet that once stood there.

From its humble beginnings, Heathrow grew rapidly to meet the demands of the modern aviation age. By the 1950s, the airport had become a key gateway for international travel, with the construction of permanent terminals like the Europa Building (Terminal 2) and the Britannic Building (Terminal 3). Over the decades, Heathrow evolved into the UK’s largest airport, handling millions of passengers annually. However, its growth also brought challenges, including increasing congestion and the need for expansion.

The Third Runway: A History of Controversy

The idea of a third runway at Heathrow has been under discussion for over 50 years, with successive governments proposing and withdrawing support for the expansion. The debate centres on Heathrow’s ability to handle increasing passenger numbers while balancing environmental and community concerns.

Early Calls for Expansion (1970s–1990s)

In the 1970s, as air travel became more accessible, Heathrow’s two-runway system started showing signs of strain. Initial proposals to expand the airport met resistance from local communities, who were concerned about noise pollution and the destruction of nearby villages. Instead of a third runway, authorities focused on improving terminal infrastructure to handle more passengers.

By the 1990s, with Heathrow surpassing other European airports in traffic volume, discussions about expansion resurfaced. The government commissioned several studies on airport capacity, but due to political hesitancy and strong environmental opposition, no formal plans were approved.

The Labour Government Push (2003–2010)

The first major push for a third runway came under Tony Blair’s Labour government. In 2003, a White Paper on aviation identified Heathrow as a prime candidate for expansion, arguing that without a third runway, the UK risked losing its status as an international aviation hub.

In 2008, Prime Minister Gordon Brown formally approved plans for a third runway and a sixth terminal, emphasizing the economic benefits of increasing capacity. However, these plans sparked mass protests, with groups like Greenpeace and local councils taking legal action against the expansion.

The project faced its biggest setback in 2010, when the Conservative Party, led by David Cameron, won the general election. Cameron had made a campaign pledge of "No ifs, no buts, no third runway", and his government scrapped the expansion plans shortly after taking office.

The Davies Commission and Reversal of Policy (2012–2016)

In 2012, the coalition government led by Cameron set up the Davies Commission, an independent review tasked with examining the future of UK aviation. The commission spent three years evaluating options, including expanding Gatwick Airport, creating an entirely new airport in the Thames Estuary, or adding a third runway at Heathrow.

In 2015, the commission released its findings, recommending that Heathrow’s third runway was the best option for maintaining the UK’s competitive edge in global aviation. The report cited economic benefits, job creation, and the need for increased capacity to handle projected passenger growth.

By 2016, the political landscape had shifted, with Theresa May replacing Cameron as Prime Minister. Her government endorsed the third runway, marking a complete reversal of previous Conservative opposition.

Parliamentary Approval and Legal Challenges (2018–2020)

In 2018, Parliament voted overwhelmingly in favour of the third runway by 415 votes to 119. The expansion was backed by major airlines, business leaders, and trade unions, who argued that Heathrow was reaching full capacity and risked losing traffic to European rivals like Paris Charles de Gaulle and Frankfurt.

However, the decision immediately faced legal challenges. Environmental groups, including Friends of the Earth, and local councils filed lawsuits against the project, arguing that it violated the UK’s commitments to reducing carbon emissions.

In February 2020, the Court of Appeal ruled that the third runway was unlawful, stating that it failed to consider the UK’s climate obligations under the Paris Agreement. The ruling was a major victory for environmental activists and temporarily halted the project.

In December 2020, however, the UK Supreme Court overturned the ruling, stating that the government could proceed with the expansion as long as it met future climate targets.

Renewed Momentum and Ongoing Opposition

The third runway’s return to the spotlight is driven by the government’s aim to enhance the UK’s post-Brexit global competitiveness. Proponents argue that expanding Heathrow is vital for facilitating international trade, attracting investment, and meeting future travel demands. Chancellor Rachel Reeves has positioned the project as a cornerstone of the government’s economic growth strategy, aligning it with promises of innovation and infrastructure development.

However, the proposal continues to face staunch opposition. Environmental groups warn that the runway would significantly increase carbon emissions, undermining the UK’s Net Zero commitments. Local communities are also concerned about noise pollution and the loss of homes, as the expansion would require the demolition of entire villages near the airport.

London Mayor Sadiq Khan has been a vocal critic, calling the project environmentally and economically unviable. Additionally, concerns over the financial feasibility of the estimated £14 billion expansion have been raised, with some questioning whether airlines and passengers will bear the cost through increased flight prices.

A Balancing Act for the Future

The debate over Heathrow’s third runway highlights the tension between economic ambition and environmental responsibility. As the government pushes forward, it faces the challenge of convincing sceptics that the project is compatible with a sustainable future.

With global aviation trends shifting and climate concerns growing, the third runway’s fate remains uncertain. What is clear, however, is that the battle for Heathrow’s future will continue to shape the UK’s infrastructure, economy, and environmental policies for years to come.
